We made marbled paper and had a lot of fun doing it.  In fact we enjoyed it so much fun we thought you would enjoy it too.  Here are the instructions so you can make them also.
 

Materials:
paper
cooking oil
2 colors of tempera paint
2 (500 ml) cups
2 eyedroppers
water
spoons
baking pan with sides

Art Experiment:
1.  Mix one color of paint with water in a cup until thin and watery.
2.  Mix the second color of paint with oil in the the other cup.
3.  Place the sheet of paper in the baking pan.
4.  Next use one eyedropper to drip spots of oily paint onto the paper.
5.  Then use  an eyedropper to drip oil paint on top of the watery paint spots.
6.  Tip the pan back and forth to move the paints.
7.  Watch the oily paint float on the water  to create unusual effects.

Variations:
Use more colors of paints.
Use a variety of paper textures.
Use a larger tray or pan, larger paper, and a larger dropper.

Science Concept:  Oil and water will not mix and are said to be insoluble.  When the oil paint is dripped on te watery paint, the two liquids stay separated and arrange themselves in layers according to their density.  The watery paint is most dense and forms the bottomlayer;  the oily paint is least dense and floats on the water as the top layer.
